当如上所述将处理盒19附接到机壳2上时,与处理盒19和机壳2的附接相关,接合构件65由约束位置移到非约束位置,因此对显影盒20从框架50拆卸的约束由接合构件65消除。 As described above, when the process cartridge 19 is attached to the casing 2, the process cartridge 19 attached to the housing 2 and the access related, engagement member 65 from the restraint position to a non-binding position, the developing cartridge 20 from the frame 50 Removal of constraint by the engaging member 65 to eliminate. 因此,无需在从机壳2中拆卸显影盒20时改变接合构件65的位置,从而从机壳2移去显影盒20时能提高可操作性。 Thus, without changing the position of the engagement member 65 in the developing cartridge 20 is detached from the cabinet 2, so that when the housing 2 is removed from the developing cartridge 20 can improve operability.

为了将处理盒19从机壳2移去,从前面操作突起柄56,以沿安装通道47向前移动处理盒19。 In order to remove the process cartridge 19 from the housing 2, projecting from the front operating lever 56 to move along the mounting channel 47 of the process cartridge 19 forwardly. 然后,在脱离接合操作部分69经过柱形构件79上方之后,接合操作部分70接触柱形构件79,而根据处理盒19的移动,接合操作部分70的下端部分被柱形构件79向上推动。 Then, the operation portion 69 in the disengaged after the upper cylindrical member 79, the contact portion 70 engaging the cylindrical operation member 79, while the process cartridge 19 in accordance with the movement, the lower end of the joining operation portion 70 is a cylindrical member 79 is pushed upward. 这样,接合构件65绕支撑轴64转动,使接合构件65的接合部分68与接合突起66接合,从而由接合构件65建立约束状态(图2B)。 Thus, the engagement member 65 is rotated about the support shaft 64, the engagement member 65 engaging portion 68 engaged with the engaging projection 66, thereby establishing a constrained state (FIG. 2B) by the engagement member 65.

当处理盒19如上所述从机壳2移开时,与处理盒19从机壳2的拆卸相关,接合构件65的位置从非约束位置回到约束位置,从而使显影盒20从框架50拆卸由接合构件65受到约束。 When the process cartridge 19 is removed from the housing 2 as described above, associated with the process cartridge 19 is detached from the housing 2, the position of the engagement member 65 from the restraint position back to the non-binding position, so that the developer cartridge 20 detached from the frame 50 65 is constrained by the engaging member. 因此,在从机壳2拆卸显影盒20,例如为了清理卡纸的时候,就无需改变接合构件65的位置,从而从机壳2移去处理盒19时能提高可操作性。 Thus, the housing 2 detached from the cartridge 20, for example, when cleaning a paper jam, there is no need to change the position of the engagement member 65, so that the housing 2 is removed from the process cartridge 19 is able to improve the operability. 此外,在将处理盒19与机壳2分离的状态下,可以防止显影盒20轻易地从框架50上拆卸。 Further, the process cartridge 19 in the housing 2 and a separated state, the developing cartridge 20 can be prevented easily detached from the frame 50. 结果,可防止由于从框架50上拆卸显影盒20而造成感光鼓21暴露,进而能防止在处理盒19与机壳2分离的状态下损坏感光鼓21。 As a result, since detaching the developing cartridge can be prevented from causing the upper frame 50 20 the photosensitive drum 21 is exposed, and thus the process cartridge 19 can be prevented and damage to the housing 2 under a state separated from the photosensitive drum 21.

为了如图3中所示那样在使处理盒19留在机壳2中时将显影盒20从处理盒19移开,在手动接合构件72的钩子部分74从突出部分78脱离接合以由手动接合构件72释放约束状态之后,从前面操作显影盒柄63,向前移动显影盒20。 In order to make as shown in FIG. 3 in the process cartridge 19 remain in the housing 2 when the cartridge 20 is removed from the developing process cartridge 19, the hook portions 72 of the manually engageable member 74 is disengaged from the projecting portion 78 to engage a manually after the release restriction member 72 state, operation of the developing cartridge from the front handle 63, the cartridge 20 moves forward. 应该理解,在将显影盒20从处理盒19移开时,接合构件65处于非约束状态。 It should be understood that, when the developing cartridge 20 is removed from the process cartridge 19, the engagement member 65 in a non-constrained state. 在将处理盒19附接到机壳2中时,为了把显影盒20附接到处理盒19上,从前方操作显影盒柄63使显影盒20向后移动。 When the process cartridge 19 is attached to the housing 2, to the developing cartridge 20 is attached to the process cartridge 19, the developing cartridge from the front of the operating handle 63 of the developing cartridge 20 is moved rearwardly. 然后,手动接合构件72的钩子部分74与突出部件78接合而由手动接合构件72建立约束状态。 Then, the hook member 72 of the manual engagement portion 74 and the engagement projecting member 78 constrained state established by the engaging member 72 manually. 在处理盒19与机壳2分离的状态下,以与上面类似的形式可以将显影盒20附接到处理盒19上和从处理盒19拆卸。 In the process cartridge 19 and the housing 2 separated state, similar to the above to form the developing cartridge 20 can be attached to and detached from the process cartridge 19 on the process cartridge 19.

在上述处理盒19中,显影盒20从框架50上的拆卸可以由手动接合构件72的钩子部分74与突出部分78的接合受到约束。 In the process cartridge 19, 20 from the frame 50 of the developing cartridge can be detached from the hook member 72 and the manual engagement portion 74 engaging the protruding portion 78 is restrained. 这样,在处理盒19与机壳2分离的状态下能进一步约束显影盒20从框架50的拆卸。 Thus, in the separated state of the process cartridge 19 and the housing 2 can be further constrain the cartridge 20 is detached from the frame 50. 结果就能进一步防止感光鼓21暴露并受到损坏。 The results can be further prevented from the photosensitive drum 21 is exposed and damaged.

可以通过简单的手动操作使手动接合构件72转动来实现钩子部分74与突出部分78接合和脱离接合。 It can be made manually engageable member 72 is rotated to achieve the hook portion 74 and the projecting portion 78 engages with disengaged by a simple manual operation. 相应地,在从机壳2拆卸处理盒19的状态下,显影盒20可以受到约束而不会从框架50上拆卸下来,并且在从机壳2拆卸显影盒20的过程中不会丧失可操作性。 Accordingly, in a state detached from the housing 2 of the process cartridge 19, the developing cartridge 20 can be restrained from detached from the frame 50, and in the process from the casing 2 of detaching the developing cartridge 20 is operable without losing sex.

在激光束打印机1中,由于机壳2上设有转印辊34,当将处理盒19从机壳2上拆卸时,感光鼓21面向转印辊34的部分暴露在外面。 In the laser beam printer 1, since the upper case 2 is provided with a transfer roller 34, when the process cartridge 19 is detached from the casing 2, the photosensitive drum 21 facing the exposed portion of the transfer roller 34. 所以,当在处理盒19从机壳2上拆卸的状态下从框架50分离显影盒20时,进一步暴露感光鼓21面向显影盒20的部分,即感光鼓21的暴露部分扩大。 Therefore, when the process cartridge 19 is detached from the housing 2 from the state separated from the frame 50 of the developing cartridge 20, is further exposed portions of the photosensitive drum 21 to face the developing cartridge 20, i.e., the exposed portion of the photosensitive drum 21 is expanded. 在处理盒20从机壳2上拆卸的状态下,当由接合构件65与接合突起66的接合及手动接合构件72与突出部分78的接合约束了显影盒20的拆卸时,可以防止感光鼓21的暴露部分扩大。 In the process cartridge 20 is detached from the casing 2 state, when the engaging member 65 engages with the engaging projection 66 and the manual engagement member 72 engaging with the projecting portion 78 of the developing cartridge constraint disassembly 20, the photosensitive drum 21 can be prevented the exposed portion of the expansion. 相应地,可以减少感光鼓21暴露部分损坏的可能性。 Accordingly, it can reduce the likelihood of the exposed portion of the photosensitive drum 21 is damaged.

由于鼓柄56和显影盒柄63分开设置,在将处理盒19附接到机壳2上及从机壳2上拆卸处理盒19时操作突起柄56,在将显影盒20附接到框架50上及从框架50上拆卸显影盒20时操作显影盒柄63。 Since the drum 56 and the developing cartridge lever handle 63 is provided separately, the process cartridge 19 is attached to the housing 2 and the process cartridge detachable from the housing 219 during operation lever projection 56, in the developing cartridge 20 is attached to frame 50 and detaching the developing cartridge from the upper frame 50 of the developing cartridge 20 is operating handle 63. 也就是,可根据情况需要使用突起柄56和显影盒柄63。 That is, it may be desirable to use the handle projection 56 and the shank 63 of the developing cartridge according to the situation. 这样,处理盒19与显影盒20在装拆过程中可以进一步提高可操作性。 Thus, the developing process cartridge 19 in the cartridge 20 during assembly and disassembly can be further improved operability.

此外,由于突起柄56和显影柄63的设置使其能从前面操作,所以可以更便捷地从机壳2的开口44操作突起柄56与显影柄63。 Further, since the projection 56 is provided the shank 63 and the shank so that the developing operation from the front, it is possible to more easily handle projection 56 and the developing operation lever 63 from the opening 44 of the housing 2. 因此,在将处理盒19与显影盒20附接到机壳2上及从机壳2上拆卸时的可以进一步提高可操作性。 Thus, when the detachable process cartridge 19 and the developing cartridge 20 is attached to the housing 2 from the upper case 2 and the operability can be further improved.
